If you have a Gaussian PSF, then how can you determine resolution
(resolvability) using the Raleigh criterion? As I understand the
Raleigh criterion says the maximum of one PSF must sit on top of the
minimum of the neighbor for them to be "just" resolved. This is OK for
a sinc-like PSF but what about a Gaussian PSF which doesn't even have
a minimum?
It's easy to do the mathematics yourself. Just add two Gaussian
functions separated by a distance that just shows a dip between the
two peaks.
By the way, how do you get a Gaussian point spread function?
